Androgens are derivatives of
cyclopentano-perhydrophenanthrene. Endogenous androgens are C-19 steroids with a
side chain at C-17, and with two angular methyl groups. Testosterone is the
primary endogenous androgen.

Testosterone Enanthate, owing to its highly anabolic/highly
androgenic effects, tends to be used in an off-season mass cycle. Water
retention during administration of testosterone with this particular ester is
reasonably high.

Testosterone suppresses HPTA function quickly and
severely. HCG and nolvadex are considered after a cycle to stimulate normal
endogenous (natural) testosterone production within a rapid period of time at
the point of post use. Males have typically injected 400-1000mg weekly, in
conjunction with a high anabolic rated drug such as deca-durabolin or
Equipoise. Trenbolone Enanthate is also a popular addition for leaner mass
gains
